Gov. Chris Christie was passed over by Donald Trump for vice president. He didn’t get to be attorney general nor White House chief of staff. He and his closest allies were purged from Trump’s transition team. Yet Christie, whose best known job offering from the Trump White House was to be labor secretary after Trump’s first nominee failed, is in position to do the president a favor.New Jersey’s Democrat-controlled Legislature passed a bill (S3048) last week that would require presidential candidates to release their tax returns on order to get on the ballot in the state in 2020 and beyond.
